Patent EP-0317102-A1 (EP)
Inventor: BRIMHALL OWEN D
IPC: B04B15/00
Filed: 1988-10-27
Abstract: This invention relates to the ultrasound enhancement of sedimentation of particulates in a particulate-bearing fluid medium while the fluid medium is undergoing centrifugation. The ultrasound energy forms standing waves in the fluid and cause particulates in the fluid, whether solids, liquids, or gases, to agglomerate in bands. The bands approximate either the nodes or antinodes of the standing wave, depending on the density of the particulate relative to the fluid. The banded or agglomerated particulate enhances the rate of sedimentation as well as the reverse flow of supernatent by removing particulate which would otherwise impede this flow.

Abstract: The method involves impressing on the system an initial acceleration of suitable magnitude and subjecting the system to an acceleration stage of suitable duration. The direction of the acceleration is inclined to the vertical at a suitable angle so as to make the system follow a ballistic trajectory in the said gravitational field. The ballistic trajectory follows the acceleration stage and comprises an ascending phase and a descending phase whose respective durations define the total duration of the ballistic stage, i.e. the stage during which the system describes the said ballistic trajectory. The ratio between the durations of the ballistic and acceleration stages being more or less equal to the ratio between the magnitude of the initial acceleration of the system and the magnitude of the acceleration due to gravity. 
<??>The above sequence is repeated by again impressing on the system an initial acceleration at the end of each sequence, i.e. at the end of the descending phase. This repetition is carried out enough times to cover a predetermined period of time.

Abstract: This invention is directed to a process for inhibiting infection in humans by selectively modulating the expression of 
a specific cell-surface determinant, namely, the CD4 molecule on human cells, with a chemical agent. The chemical agent 
is a ganglioside composition which induces the rapid and selective disappearance of CD4 cell-surface determinants from 
human cells. By selectively modulating the expression and function of the CD4 cell-surface determinant, employing a 
ganglioside composition which induces the rapid and selective disappearance of the CD4 cell-surface determinants from 
human cells, the point of attachment and entry into the T-helper cell for viruses which infect the human cells through the 
CD4 cell-surface determinants, such as HIV, is eliminated, and the receptivity of these human cells is inhibited, without in­
hibiting other cell-surface determinants.

Abstract: Melt-processible copolymers of at least two halogenated comonomers from a defined class, especially perhalogenated comonomers, and particularly perfluorinated comonomers, of improved thermal stability are obtained by first contacting the copolymers with a stabilizing agent selected from bases (ammonia or amines) having a boiling point at normal pressure of at most 130 DEG C and tertiary alcohols having up to 8 carbon atoms, to form an intermediate, drying the intermediate at about 70-150 DEG C, and fluorinating the intermediate at a temperature between 20 DEG C and the lowest temperature at which the copolymer exhibits a solid state transition, then removing excess fluorine and by-products and recovering the stabilized copolymer. Such stabilized copolymers are useful for a variety of technically important applications, including as cladding for optical fibers, substrates for electronic components, thermal laminates, pipes, tubes, and fittings, etc.

Abstract: This invention provides a wire recovery method and apparatus therefore which can store orderly used wires, has a large wire storage capacity and can therefore provide an unmanned operation of a wire cut electric discharge machine for a long period. A wire feed speed instructed by a machining program is divided by a target wire winding radius set in advance to calculate a target drum angular speed providing a wire winding speed which is in conformity with a wire feed speed at this target radius (S4), and a wire storage drum is rotated at the target drum angular speed by a speed controller responsive to an instruction representing this calculated value through a motor (S7). As a result, the used wire is recovered into a drum while being laminated on a circular orbit inside the drum having an equal radius to a target radius.
